Hamilton discusses Button crash during rain red-flag

While the sodden spectators waited for the Montreal rain to ease, the latest F1 controversy began to swirl.

The Canadian grand prix was red-flagged for a long period whilst weather men grinned at their accurate predictions of heavy afternoon rain.

As the teams stood idle, drinking tea and eating biscuits on the grid while drivers sat in their cockpits under canvasses, Lewis Hamilton was at the back of the pits speaking about his collision with teammate Jenson Button.

McLaren’s Hamilton had to retire from the race after clashing with the sister MP4-26 amid the spray and against the pitwall.

"What’s he doing?" Button exclaimed in the radio, having clearly not seen his countryman through the spray in his mirrors.

Hamilton told reporters: "I don’t know if he could see me or not, but he just kept coming over and over," said Hamilton, who later consoled himself with a hug with pop star Rihanna.

"It was tricky conditions, I was doing the best I could to keep the car on-track, I think I had pretty good pace. Whilst I fell back behind Jenson he made a mistake into the last corner, so I got the run on him. I was on the outside I guess, I haven’t seen the footage but it felt like I was half way up the outside of him and he kept moving across, whether or not he saw me and I was in the wall," he added.
